To provide item analyses, estimates of temporal reliability and internal consistency, and examination of the sensitivity and specificity of a traumatic brain injury-screening tool.
Five hundred veterans of the wars in Iraq and Afghanistan enrolled in the study, approximately half of whom (248) volunteered. The remaining 252 participants were referred to Veteran Affairs (VA) neuropsychology or polytrauma clinics.
This psychometric study constitutes part of a larger 4-year, multisite prospective cohort study of veterans returning from Iraq and Afghanistan.
Five VA medical centers and one VA outpatient clinic.
Veteran traumatic brain injury screening tool (VATBIST), a structured diagnostic interview for traumatic brain injury; a military-oriented posttraumatic stress disorder checklist.
The VATBIST appeared to have high-internal consistency (0.77) and test-retest reliability (0.80), high sensitivity (0.94) and moderate specificity (0.59). Diagnostic odds ratios for the screening tool ranged from 12.6 for the total sample to 24, when veterans with probable posttraumatic stress disorder were excluded from analysis.
The VATBIST appears to be a reliable and valid instrument. The presence of significant posttraumatic stress disorder symptoms, however, reduces the accuracy of the measure and highlights the need for careful clinical follow-up of persons who screen positive.
提供项目分析、时间可靠性和内部一致性的估计，并检查创伤性脑损伤筛查工具的敏感性和特异性。
本研究纳入了 500 名参加过伊拉克和阿富汗战争的退伍军人，其中约有一半（248 名）自愿参加。其余 252 名参与者被转介到退伍军人事务部（VA）神经心理学或多发伤诊所。
这项心理计量学研究是一项为期 4 年、多地点前瞻性队列研究的一部分，该研究对象是从伊拉克和阿富汗返回的退伍军人。
五个 VA 医疗中心和一个 VA 门诊诊所。
退伍军人创伤性脑损伤筛查工具（VATBIST），一种用于创伤性脑损伤的结构化诊断访谈；一种面向军事的创伤后应激障碍检查表。
VATBIST 似乎具有较高的内部一致性（0.77）和重测可靠性（0.80）、较高的敏感性（0.94）和中等特异性（0.59）。该筛查工具的诊断优势比范围从总样本的 12.6 到 24，当排除患有可能的创伤后应激障碍的退伍军人进行分析时。
VATBIST 似乎是一种可靠和有效的工具。然而，存在明显的创伤后应激障碍症状会降低该措施的准确性，并突出需要对筛查阳性者进行仔细的临床随访。
